Build garage foundation (including frost skirt) yourself

Hello everyone,

I will build a garage myself. The structural engineer is still working on it and I will receive his plans shortly.

I have already dealt with the foundation including the frost skirt and rented a 2.6t mini excavator for only ONE DAY next week.

I want to proceed as efficiently as possible. Here is my plan:

[*]First, I would dig out the "trench" for the frost skirt and leave only one strip (yellow).
[*]Then I will also remove 15cm inside but leave a 30cm edge all around.
[*]My tipper can then dump the gravel onto the strip at the right place.
[*]After that, I will remove the remaining strip (yellow) with the excavator.
[*]Once the concrete skirt is poured, I only need to remove the 30cm edge inside (by hand) and can then fully spread the gravel. This way I save a second day of using the excavator.

Good idea or any objections? Did I forget anything?

Regards,
Michael

I somewhat doubt that everything will hold up as you plan. Otherwise, not the worst idea from you.

You have definitely never excavated before!

And 30 cm frost skirt? Measured from where?

If the gravel doesn’t fall into the ditch when dumped despite the edge... It probably depends on the truck driver
